Cengel's Thermodynamics is known to be student friendly, self-instructive, and easy to read and understand even for the most challenging topics with the help of attractive illustrations, examples, and real-world applications. The authors' philosophy is that the best way to learn is by practice. Special effort is made throughout the book to reinforce material that was presented earlier and to appeal to students' natural curiosity and intuition. For instructors looking to engage students and enhance their problem-solving skills, Connect offers student-friendly, accessible content, tools, and resources that develop high-level problem-solving and critical thinking skills, including New Application-Based Activities.
Thermodynamics can be defined as the science of energy. Although everybody has a feeling of what energy is, it is difficult to give a precise definition for it. Energy can be viewed as the ability to cause changes. The name thermodynamics stems from the Greek words therme (heat) and dynamis (power), which is most descriptive of the early efforts to convert heat into power. Today the same name is broadly interpreted to include all aspects of energy and energy transformations including power generation, refrigeration, and relationships among the properties of matter.
One of the most fundamental laws of nature is the conservation of energy principle. It simply states that during an interaction, energy can change from one form to another but the total amount of energy remains constant. That is, energy cannot be created or destroyed. A rock falling off a cliff, for example, picks up speed as a result of its potential energy being converted to kinetic energy. The conservation of energy principle also forms the backbone of the diet industry: A person who has a greater energy input (food) than energy output (exercise) will gain weight (store energy in the form of fat), and a person who has a smaller energy input than output will lose weight.
